Abstract:
We have analysed high-dispersion Echelle spectra (R=60000) of red
giant members of five open clusters to derive abundances for many
elements from Na to Eu. The [Fe/H] values are -0.06±0.03 for Stock
2, -0.11±0.03 for NGC 2168, -0.01±0.03 for NGC 6475, 0.00±0.03
for NGC 6991, and -0.07±0.03 for NGC 7662. Sodium is enriched in the
giants relative to the abundance expected of main-sequence stars of
the same metallicity. This enrichment of [Na/Fe] by about +0.25
attributed to the first dredge-up is discussed in the light of
theoretical predictions and recently published abundance
determinations. Abundance ratios [El/Fe] for other elements are with
very few exceptions equal to those of field giants and dwarfs, i.e.
[El/Fe]∼0.00 for [Fe/H]∼0.0. An exception is the overabundance of La,
Ce, Nd, and Sm in NGC 6991 but this is consistent with our previous
demonstration that the abundances of these s-process products vary by
about ±0.2 among clusters of the same [Fe/H], a variation found also
among field giants and dwarfs.
Description:
Selection of red giants for subsequent spectroscopic observations was
made by identifying stars having common proper motions at the putative
red giant clump in the cluster colour-magnitude diagram (CMD). The
CMDs were created from the available BV and Gaia DR2 photometric
magnitudes.
High-resolution and high signal-to-noise (S/N) ratio optical spectra
of 18 giant stars in six OCs, namely Stock 2 (3 giants), NGC 2168 (3
giants), NGC 6475 (3 giants), NGC 6991 (4 giants), and NGC 7762 (3
giants) were observed in 2016 September, October, and November with
the Robert G. Tull coude cross-dispersed Echelle spectrograph (Tull et
al. 1995PASP..107..251T 1995PASP..107..251T) at the 2.7-m Harlan J. Smith Telescope of the
McDonald Observatory. On all occasions we employed the camera with a
2048x2048 24µm pixel CCD detector and 52.67 grooves/mm Echelle
grating with exposures centred at 5060Å in order 69. We secured two
to four exposures of cluster giants in our target list (Table 1) with
each exposure limited to 20-30min to minimize the influence of cosmic
rays and to acquire a global S/N of above 100.

Note (2): We derived the star's photometric effective temperature, by
substituting the dereddened photometric colours into the infrared
flux method based colour-temperature calibrations of Alonso, Arribas
& Martinez-Roger (1999A&AS..140..261A 1999A&AS..140..261A).
Note (3): The photometric estimates of surface gravities, were made by
incorporating the heliocentric distance of the cluster, photometric
temperature, bolometric correction, cluster turn-off mass, and the
solar parameters of Teff=5777K and logg =4.44cm/s2 into the
well-known logg-Teff relation (Reddy et al. 2012MNRAS.419.1350R 2012MNRAS.419.1350R,
Cat. J/MNRAS/419/1350).

Note (1): Flag as follows:
* = We excluded the barium abundance of the star 310 in NGC 2168 in
calculating the cluster mean [Ba/Fe] value due to the star's rapid
rotation (Vrot∼12km/s) which may lead to turbulent superficial stellar
layers from where the BaII lines emerge. As a result, the inclusion of
microturbulence derived from Fe lines in the spectrum synthesis of a
BaII line is insufficient to represent the true line broadening imposed
by relatively turbulent upper photospheric layers on the BaII line,
which may result in a serious overestimation of the Ba abundance by
standard LTE abundance analysis (Reddy & Lambert 2017ApJ...845..151R 2017ApJ...845..151R).

Note (1): For all giants in this and earlier papers in this series, the Na
abundances derived assuming LTE were corrected for non-LTE effects
using the grids of Lind et al. (2011A&A...528A.103L 2011A&A...528A.103L).
The corrections were derived on a line-by-line basis, using the
stellar parameters (Teff, logg) and the EWs of Na lines (5688.20,
6154.22, and 6160.74Å) of each star as input to the interactive
non-LTE data base.
Note (2): The non-LTE corrections for Al were computed using the extensive grids
of abundance corrections discussed in Nordlander & Lind
(2017A&A...607A..75N 2017A&A...607A..75N). The non-LTE Al abundance calculations were
carried out using the stellar parameters and LTE Al abundances for
the 7835, 7836, 8773, and 8774Å lines as input to the source code
of Nordlander & Lind (2017A&A...607A..75N 2017A&A...607A..75N).
